Bug 301623

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I uninstalled and reinstalled KDE but when I tried to log into the Plasma desktop, it failed to load at all. I could right click and get a very limited menu so I logged out and tried installing Kubuntu instead of the separate KDE files and that got the desktop back the way I used to have it. Then I had been changing the desktop settings around after installing KDE when Plasma crashed a second time and this report got generated.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
